Benefits of technology

The present invention is a modified animal litter that includes a special material that absorbs liquid and a substance called peroxide. This litter has the added benefit of consistently and effectively reducing malodors caused by animal waste.

Problems solved by technology

These materials become tacky when wetted, thereby forming a “clump” that is easily removed from a litter box.
Many animals, especially felines, will often refuse to use a litter box that is not kept scrupulously clean.
However these materials have very little, if any, deodorizing properties.

Preparation of Acid-Activated Bentonite

[0042]West Colony sodium bentonite (325 g) was added equally to two sets of flasks. Each set contained three 5-liter round bottom flasks, and each flask contained respectively 4 liters of 1 N, 2 N, or 18 N of sulfuric acid with a stir bar. Each flask was attached to a condenser in a reflux set-up and one set was heated to 60° C., while the second set was heated to 100° C. for 2 hrs with stirring. The heating was accomplished with a temperature-controlled heating mantle and a stir plate. After cooling, the mixture was decanted to remove the acidic aqueous layer. The remaining mixture from each flask was separately washed with deionized water and filtered by suction filtration. The final filtrate after 3 washings showed a pH of 2 using a pH meter. The solids were dried in an oven at 110° C. for 2 hrs or until dry.

Sniff Testing of Acid-Activated Bentonite Added With Cat Urine and Synthetic Cat Fecal Malodor

[0047]Acid-activated bentonite (60 ml) samples that were prepared from Example 1 were each placed in a 8 oz. glass jar with and without 10 v / v %, magnesium peroxide, and the jar was covered with aluminum foil and with holed caps.

[0048]Controls in this example included untreated sodium bentonite with and without 10 v / v %, magnesium peroxide. Cat urine from Sharp Veterinary Research (Texas) was utilized and synthetic cat fecal malodor was prepared. For the cat urine malodor test, the processed cat urine was heated to 35° C. then added to the litter jars each day for three days (5 ml / jar / day) using a 60 ml syringe. Seven panelists rated the malodor at Day 5 (Day 1=first addition of urine) relative to the controls. For the cat fecal malodor test, 1 drop (˜0.03 g) of synthetic fecal malodor was combined with 5 grams of synthetic feces substrate and added to the litter jars (the litter samples co...

Abstract

A chemically modified animal litter that is comprised of at least one acid-activated liquid absorbing material and at least one peroxide, wherein the litter provides a surprisingly steady and consistent malodor inhibition.

Description

FIELD OF THE INVENTION[0001]The present invention relates to animal litters, and in particular to animal litters that have been chemically modified, wherein the litter is found surprisingly effective in mitigating urine and fecal odors.BACKGROUND OF THE INVENTION[0002]In an effort to efficiently and effectively collect animal urine and / or feces, various methods and compositions are known to utilize absorbent materials in litter boxes and animal cages. In particular, clays (primarily bentonite) have been used as a base material for absorbent animal litters for some time. These materials become tacky when wetted, thereby forming a “clump” that is easily removed from a litter box. Many animals, especially felines, will often refuse to use a litter box that is not kept scrupulously clean. Clumpable animal litters facilitate the ease of cleaning, because otherwise the litter box has to be periodically dumped and refilled to maintain appropriate cleanliness.[0003]Clays such as those based...
